An upcoming version replaces Dogmeat with Black Phillip.

The world of “Fallout 4” is as open as they come, with endless side quests, oddball characters and other distractions to while away the hours in the wasteland. Thanks to a new mod, the post-apocalyptic RPG can now double as something akin to a horror film in the vein of “The Witch.”

That’s fitting, as the long-standing series owes much of its aesthetic to another movie: “Mad Max.” Among the features in the “Pilgrim — Dread the Commonwealth” mod are a greyer color palette, film grain and new soundtrack, but perhaps most exciting of all is an upcoming addition that will swap out the faithful canine sidekick Dogmeat with none other than Black Phillip himself. Wouldst thou like to game deliciously?
